A few readers have written asking about odd denials when trying to use Juniper VPNs. Turns out they released a Product Support Notification (subscription required) about their host check feature which fails on endpoints that have a local date set 12/31/2013 or later. There are working on a fix but as a workaround, you can change the local date on the PC, disable host checker verification all together or create a manual host checker process that disables checking firewall, anti-virus and/or anti-spyware predefined checks. Juniper plans to release a fix some time between 12/31 and 1/3/14.
